It was a $10M machine at that time, so it was critical that for us to produce anything, that our homework and drawings were right.&nbsp; It usually took 8-12 hours to produce an item, but it came out well.</p><p><br /></p><p>I suppose that technology and costs have advanced since the 90&#039;s ( <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie2" alt=";)" unselectable="on" unselectable="on" /> ), that would enable someone to have relative cheaper access to these capabilities, and to replicate a coin that would be economically viable to invade a market...
